Lifting capacity of single beam crane
After the single-beam crane lifting limiter device is installed, the corresponding alarm scale fixed load should be set. This method is nothing more than suspending the load of a similar alarm weight on a single-beam crane, hoisting the goods off the ground, and turning the load control button on the dashboard until the flashing alarm signal is announced.
Secondly, adjust the potentiometer button of the digital instrument to display the number or text equivalent to the actual lifting weight of the single girder overhead crane, and set the additional load in the same way. When the single girder crane is overloaded, it can quickly block the ascending loop and power supply. After adjusting the potentiometer buttons, they should be locked immediately, and the buttons should be sealed with paint. Do not turn the buttons for special adjustments.
The single-girder crane was originally a new product developed by introducing German equipment. It has the advantages of novel structure, application, simplicity, flexible use, and large operating space. This machine is an energy-saving and efficient material-improving transportation machinery, which can be widely used in factories, mines, busy production lines, tooling supporting lines, etc., machine tools and heavy objects are hoisted and transferred at the warehouse wharf. The following are the safety requirements of the overload limiter Single beam crane should be added:
The overall error of the lifting limiter is not more than 8% for mechanical type and not more than 5% for electronic type;
When the load reaches 90% of the additional target lifting capacity, a warning signal should be announced;
After the single-beam crane is equipped with a load limiter, it should be adjusted and set according to its performance and accuracy. When the load is greater than the additional lifting capacity, it should be able to automatically block the upward power supply and announce a stop signal.
